Technical field:
---the present invention relates to the blowdown technology without the dirty valve of concentrated water drainage, specifically a kind of reverse osmosis membrane without dense water power magnetic wash water valve or nanofiltration membrane water purifier.
Technical background:
---current reverse osmosis membrane both domestic and external or nanofiltration membrane device, all need to carry out concentrated water drainage dirt, otherwise just there will be concentration polarization phenomenon, there is filtering membrane short period of time blockage problem, appliance life is related to owing to adopting the dirty valve of concentrated water drainage, time has been grown and has easily occurred the defects such as wash water valve burns out, improve pre-sales and after cost, therefore, adopt pure water or pure water inlet passage 2A2 that former water pressure is installed to be less than or equal to but the associating pressure of stock solution water pressure and at least 1 pump is greater than again the technology that at least 1 check valve of unidirectional elastic force and 0 or at least 1 perforate restrictor or flow-limiting valve or waste water ratio can replace traditional concentrated water drainage dirt valve, for cost-saving and maintenance and repair cost, there is good meaning.
Utility model content:
The utility model content that a kind of reverse osmosis membrane without dense water power magnetic wash water valve or nanofiltration membrane water purifier adopt is as follows: 1, upper level filter core or stock solution water interface are connected successively with connecting passage 1A, reverse osmosis membrane or nanofiltration membrane filter core, dense water out passage 2A1; The pure water inlet end of reverse osmosis membrane or nanofiltration membrane filter core is connected with pure water or pure water inlet passage 2A2; Pure water or pure water inlet passage 2A2 have at least 1 check valve and 0 or at least 1 perforate restrictor or flow-limiting valve or waste water ratio; Stock solution water pressure is less than or equal to the elastic force of at least 1 check valve namely under stock solution water pressure, and at least 1 check valve is still in closing condition; Meanwhile, the pressure sum that stock solution water pressure and at least 1 pump produce is greater than the elastic force of at least 1 check valve, and namely under the associating pressure of stock solution water pressure and at least 1 pump, at least 1 check valve is open and opens; At least 1 pump is positioned on connecting passage 1A or dense water out passage 2A1.
Technical problem to be solved in the utility model:
The purpose of this utility model overcomes the deficiencies in the prior art, adopt pure water or pure water inlet passage 2A2 that former water pressure is installed to be less than or equal to but the associating pressure of stock solution water pressure and at least 1 pump is greater than again the technology that at least 1 check valve of unidirectional elastic force and 0 or at least 1 perforate restrictor or flow-limiting valve or waste water ratio can replace the dirty valve of traditional concentrated water drainage, with maintenance and repair cost, there is good effect for cost-saving.
Technical requirements of the present utility model is such:
(1), shell, drainage layer, sealing material such as seal gum and plastics, valve all adopt sanitation-grade or food grade materials.
(2), the pressure of former water, stoste is 0-0.5MPA or more pressure.
(3), need to determine whether to need the accessory such as entering water electromagnetic valve and high-voltage switch gear, low-tension switch, waste water ratio according to actual hydraulic pressure hydraulic pressure etc.
The technical scheme that the utility model technical solution problem adopts:
1, upper level filter core or stock solution water interface are connected successively with connecting passage 1A, reverse osmosis membrane or nanofiltration membrane filter core, dense water out passage 2A1; The pure water inlet end of reverse osmosis membrane or nanofiltration membrane filter core is connected with pure water or pure water inlet passage 2A2; Pure water or pure water inlet passage 2A2 have at least 1 check valve and 0 or at least 1 perforate restrictor or flow-limiting valve or waste water ratio; Stock solution water pressure is less than or equal to the elastic force of at least 1 check valve namely under stock solution water pressure, and at least 1 check valve is still in closing condition; Meanwhile, the pressure sum that stock solution water pressure and at least 1 pump produce is greater than the elastic force of at least 1 check valve, and namely under the associating pressure of stock solution water pressure and at least 1 pump, at least 1 check valve is open and opens; At least 1 pump is positioned on connecting passage 1A or dense water out passage 2A1.
Realize concrete mode and requirements more of the present utility model:
1, all possess water supply or feed flow user=, as long as pipeline hydraulic pressure or hydraulic pressure to reach between 0-0.8MPA or more standard, comparatively ideal filtration, purification and effluent function can be realized.
The beneficial effect that the utility model produces is:
---overcome the deficiencies in the prior art, adopt pure water or pure water inlet passage 2A2 that former water pressure is installed to be less than or equal to but the associating pressure of stock solution water pressure and at least 1 pump is greater than again the technology that at least 1 check valve of unidirectional elastic force and 0 or at least 1 perforate restrictor or flow-limiting valve or waste water ratio can replace the dirty valve of traditional concentrated water drainage, with maintenance and repair cost, there is good meaning for cost-saving.
Accompanying drawing illustrates:
Fig. 1 is sectional view of the present utility model.
As shown in the figure: 1, upper level filter core or stock solution water interface, 1A, connecting passage 1A, 1B, 0 or at least 1 pump, 2, reverse osmosis membrane or nanofiltration membrane filter core, 2A1, dense water out passage 2A1,2A2, pure water or pure water inlet passage 2A2,2D, at least 1 check valve, 2F, 0 or at least 1 perforate restrictor or flow-limiting valve or waste water ratio.
Embodiment:
The utility model embodiment 1 is described below in conjunction with accompanying drawing and a preferred embodiment:
Fig. 1 a kind ofly analyses and observe diagram without the dense reverse osmosis membrane of water power magnetic wash water valve or the structure of nanofiltration membrane water purifier:
(1), device virgin state: all terminal valves are all in closure state.
(2) process of the dirty valve of traditional concentrated water drainage, is replaced:
Former water enters into connecting passage 1A (1A) from upper level filter core or stock solution water interface (1), unidirectional elastic force due at least 1 check valve (2D) is greater than the pressure of former water or stoste, now, at least 1 check valve (2D) is not open and opens, be in closing condition, when starting at least 1 pump (1B), under the dynamic action of pump, the pressure sum that the pressure of former water or stoste and at least 1 pump (1B) produce is greater than the unidirectional elastic force of at least 1 check valve (2D), now, at least 1 check valve (2D) is open and opens, dense water flows out from dense water out passage 2A1 (2A1), thus play the effect opening stream and cutout of the dirty valve of traditional concentrated water drainage, when manufacturing pure water or nanofiltration water water is full, high-voltage switch gear is by least 1 pump (1B) power dump, now, the pressure of at least 1 pump (1B) reverts to zero gradually, the unidirectional elastic force of at least 1 check valve (2D) is greater than the pressure of former water or stoste, at least 1 check valve (2D) bounces back closedown once more, thus stop the waste of dense water.Concentrated stream amount is controlled in the effect of 0 or at least 1 perforate restrictor or flow-limiting valve or waste water ratio (2F) better well, play the effect being equivalent to waste water ratio and effect that prevent dense water from wasting, when concentrated stream amount meets the requirements, this at least 1 perforate restrictor or flow-limiting valve or waste water ratio (2F) can be cancelled.
